DEVICE FOR OPERATING VALVES.

SPECIFICATION forming part of Letters Patent No. 300,131, dated June 10,1884.

Application filed September ."i, 1883. (No model.)

To aZZ whom it may concern.-

Be it known that I, J OSEPH REIGHMANN, a citizen of the United States ofAmerica, re siding at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Devicesfor Operating Valves, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to an improved device for regulating the flow ofliquids under high pressure.

The object of the invention is to so arrange theinduction and eductionvalves of such an apparatus that they will both be connected to andoperated by the same mechanism, one at least being always closed; and tothe accomplishment of the above the invention consists in the novelconstruction and arrangement of certain of the parts, and in certaincombinations of such parts, as will be described and claimed.

Reference will be made to the accompanying drawings, in which Figure 1isa vertical section showing the valves and their connections; Fig. 2, asection on line 1 1 of Fig. 1; Fig. 3, a top plan view; Fig. 4., a sideelevation showing a modified arrangement of the valve-rods; Fig. 5, atop plan of the same; Figs. 6, 7, and 8, views of a modification of theinvention.

Like letters refer to like parts in each view.

A represents a casing provided with suitable induction and eductionpipes, a, for the admission and expulsion of the motive agent, and apipe, a, connecting such casing with the apparatus to be driven.

Formed within casing A are partitions b I), through which suitableopenings are formed for the admission of the motive agent to and itsexpulsion from pipe 01.. These openings are closed by double-headedvalves 0 c, the horizontal portions of partitions b 1) serving as seatsfor said valves.

B B represent the valve-rods, which pass through suitablestuffing-boxes, (Z d, and have cast on their lower ends rings or flangese a, which enter the upper heads of valves 0 c, and are secured theretoby screw-threaded caps ff, as shown. Valve-rods B B have forked upperends, into which a lever, O, is inserted, said rods being pivoted tothis lever passes between the forked upper end of a standard, D, whichis mounted upon the upper face of easing A, and said lever extends bysuitable pins, as shown. Lever C also out a sufficient distance to beconveniently b, formerly closed by said valve, and through pipe a to theapparatus to be operated. IVhen it is desired to reverse the action ofthe apparatus, the lever O is raised to itsnormal position, whichcarries the valve 0 back to its seat and shuts off the supply, and, theleve being still further raised, the fulcrum thereof is formed at thepoint where Valve-rod B is connected thereto, and the valve-rod B andits valve 0 raised. This opens the ports made in partition b, and allowsof the escape of the exhaust therethrough, and through the outlet-pipea. While either valve is openthe friction upon its rod, where said rodpasses through the stuffingbox referred to, is sufficieut to keep it inits elevated position; but when it is desired to close such valve andopen the remaining one, the overpressure upon the closed valve is such,owing to the fact that the upper heads-of both valves are of larger areathan the lower heads, that such closed valve will be pressed and heldfirmly to its seat until the open valve is completely closed, thuspreventing all danger of having both valves open at the same time; and,further, when the open valve has been closed and it is desired to openthe remaining one, a moderate amount of power must be exerted toovercome the overpressure on such valve, and the valve just closed ispressed firmly to its seat thereby.

In Figs. 4 and 5, I have'shown a modified form of the manner ofconnecting the valverods to the'lever. In this construction the rods arepassed through slots 9 g, made in the lever G, and said lever pivoted inthe upper end of an auxiliary standard, E, as shown, the fulcrum of saidlever being always at the point where it is pivoted in this standard E.Upon the upper ends of valve-rods B B are formed weights F F. WVhen thehandle end of lever O is depressed, the valve-rod B is raised by saidlever coming in contact with the under face of its weight F, the valve 0of valve-rod B being at the same time held firmly on its seats by theweight F. \Vhen the le ver is again brought to its normal position, thevalve-rod B is lowered by gravity, and as the handle end of said leveris raised valve-rod B is carried up and the exhaust allowed to escape.

In Figs. 6, 7, and S, I have shown a construction by means of which myinvention may be adapted to admit the motive agent to both ends of acylinder to operate the piston from opposite sides. As shown in thisconnection, casing A is provided with pipes h h, for the supply andexhaust of the motive agent, and with pipes 11 i, for connecting saidcasing with opposite ends of the cylinder. jj are the valves forregulating the flow of the supply, and 7c 70 valves regulating theexhaust,cach of such valves having suitable seats in the partitionsformed within the casing, and the supply-valves being separated from oneanother by a partition, Z, as also are the exhaust-valves, saidpartition extending the entire length of the casing. At their upper endsthe rods of valves j and 7c are connected by a yoke, m, so as to causethese two valves to'rise and fall together, the rods of valves j and Itbeing likewise connected by a yoke, m, as shown. The yoke m is connectedby an while the exhaust escapes from the other. The

handle end of the lever being then raised, the fulcrum is formed at thepoint where the arm a is connected with arm 0, and the valves j and kare opened, the valves j and It being first closed and held firmly totheir seats by the overpressure, as described in connection with themain invention, and thus the supply and exhaust is admitted to andexpelled from the opposite ends of the cylinder.

Having thus described my invention, what I claim as new therein, andthat for which I desire to secure Letters Patent, is-

The combination, with the double-headed valves 0 c and their rods 13 B,of the lever O, fulcrumed in the upper ends of said rods, whereby inopening one valve the fulcrum of said lever is transferred to the othervalve, substantially as and for the purpose set forth.

In testimony whereof I afiix my signature in presence of two witnesses.

JOSEPH REICHMANN.
